Soil erosion is a manifestation of soil degradation, however, this process in certain environments can be accelerated by natural characteristics and / or by anthropic action. In Brazil, millions of tons of agricultural soil are lost each year due to poor soil management, and in this way areas that were previously arable become degraded by carrying the top and most fertile soil layers. These losses cause environmental and economic losses, being necessary to better dimension these processes of environmental degradation, to characterize the erosive processes. In this sense, the objective of this work was to diagnose and analyze the erosive processes at the Campus Rural Experimental Station, in São Cristóvão, Sergipe. For this purpose, the Universal Soil Loss Equation (EUPS) was used and, in addition, an assessment form of the erosive processes presents in the studied area. The collected data were worked statically by the Kriging Method. The study area is located at the Campus Rural Experimental Station, of the Federal University of Sergipe, in the locality known as Timbó, in the municipality of São Cristóvão, Sergipe, with an area of approximately 182.27 hectares. Soil losses ranged from 1.8615 to 24.1718 t / ha.year, with the Plinthossols class being predominant. The factors that most influenced the results were the LS - Slope and ramp length factor and CP- Coverage factor and Conservationist practices factor.
